Year 3 - American Beaver
The North American Beaver (Castor Canadensis) is the largest rodent in North America. Beavers are well adapted to a semi aquatic lifestyle with large, flat, wide tails which act as a rudder when swimming along with their webbed hind feet.
Interestingly, Beavers can stay submerged in water for up to 15 minutes, as their thick and oily waterproof coat with fine underhairs and outer protective guard hairs help them to conserve heat when immersed in cold water. The teeth of the North American Beaver are disproportionately large, with upper incisors that are not only bright orange in colour, but also at least 5mm wide and 20-25mm long. They grow continuously throughout a Beaver’s lifetime and are vital to their survival, helping them to cut through hard woods and enjoy a herbivorous diet of bark and cambium. Their favourites include maple, poplar, beech, birch, alder and aspen trees.
Did you know Beavers are second only to humans in their ability to modify their environment and surroundings? Beavers are engineers! In their family groups called colonies they build dams to slow down the flow of water in rivers and streams then construct lodges for shelter which they strategically built in accordance with the speed of the water. These creatures play a vital role in preservation of our ecosystem maintaining wetlands which slow the flow of floodwaters and raising the water table which supports the water purification process.
